C64E boards which are fully equipped are very easy to get, on the other hand. So why not use one of them, maybe exchange the cartridge connector for a vertical one, and put this one into the 64GS, with a copy of the 64GS ROM. Since those ROMs are 27128 Eprom compatible, it's a very easy task to do this. Keep the unmodified 64GS board somewhere in a safe place ;-) About the Magic Voice: I analyzed the startup sequence in the ROM to some extent, when I was in the process of repairing my cartridge. It only has 16k ROM, and starts up in a strange memory configuration. It uses Ultimax features to replace the kernal ROM, but only very few code will execute from that location. Most of it is copied to RAM and just contains the speech control program that resides at $c000 after the initialization procedure. The Magic Voice restores the C64 memory configuration completely, and even starts a EXROM or EXROM/GAME cartridge that is installed in its cart port. I think even Ultimax cartridges will work, I remember to see some tests for it in the MV ROM code. Nicolas - This message was sent through the cbm-hackers mailing list.
